4.2.2 Opening a new hole
Choose a central area of the roof between
two side members and trace the outline of a
395 mm square with a felt-tip pen (fig.2) and
(fig. 4 ref. 1).
Cut the new opening in the roof carefully with
a saw: be careful not to cut any electrical
wires (fig. 4 ref. 2).
Fix a reinforcement frame around the
opening (fig.
5)
.
Use protective gloves and
goggles before using electrical tools or
handsaws.
4.2.3 Power lead
To power the air conditioner it is necessary to
lay a 3-pole lead (phase-neutral-earth): each
wire must have a minimum cross-section
of 2.5 mm
2
. At one end the lead must be
connected to a thermomagnetic switch
inside the electrical distribution board of the
vehicle; the other end must reach the
aperture on the roof, protruding from the hole
on the reinforcement frame by about 50 cm:
this additional length makes it easier to
connect up to the air conditioner (fig. 6).
